"This is a big, major problem that almost all policymakers should really recognize — which is the United States now has the highest corporate tax rate in the world," Moore told J.D. Hayworth on "America's Forum" on Newsmax TV on Monday.

Walgreens is about to acquire the European drugstore chain Alliance Boots and is considering doing a corporate inversion, also called a tax inversion, which means changing the tax domicile of the company to the overseas country. If that were to occur, the U.S. would no longer be able to tax earnings overseas, the San Francisco Chronicle reported.

"It's sending jobs overseas to countries like Singapore and countries like Taiwan and countries like Indonesia and Switzerland and other countries that have lower rates because tax rates matter and investment flows to those countries on balance that have lower tax rates," he added.

According to Moore, this is the third "major iconic American company in the last month or so that has talked about moving out of the United States."

Medtronic Inc., a major medical-device maker, is planning to move to Ireland, and pharmaceutical giant Pfizer Inc. is "investigating" a move to Ireland.

"We're not going to have any corporations or jobs left in this country if we don't do something about our corporate tax rate," Moore contends.
